LUBRIGATOIR.

Specification of Letters Patent.

Patented Sept. 5, 191a.

Application filed January 19, 1916. Serial No. 72,995.

To all w hom it may concern Be it known that I, RUssELL P. SoHUYLnR,

J a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a description.

My invention belongs to that general class of devices in which the lubricant is automatically delivered in measured quantities to the cooperating part, the operation of said cooperating part serving to actuate the lubricator.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a vertical section of my improved lubricator; Fig. 2 is a transverse section in line 22 of Fig. 1; Fig. 3 is a transverse section in line 3-3 of Fig. 1; Fig. 4; is an elevation of the valve used in my lubricator, and Figs. 5 and 6 are plan views of vaporizing plates which may be used with my device, to regulate the degree of vaporization of the lubricant as it is delivered to the cooperating partsm In the drawings, 1 is a suitable oil receptacle of well known form, provided with a cap 2, having formed therein an intake opening 3 covered by the slide 4. The internal tube 5 has centrally seated therein a stem 6, provided with a button 7 controlled by the spring 8. The lower end of the stem 6 terminates in a needle valve 9. This is given a longitudinal movement by reason of the stem having a threaded connection with the cap 2, whereby a rotation of the stem by means of the button 7, will control the operation of the needle valve. The lower end of the cup has a duct 10 formed therein, theupperpart providing a seat cooperating with the needle valve. One or more apertures l1 permit the lubricant to enter the tube 5, and from thence pass by the needle valve downwardly to acha'mber 12.

A substantially pear-shaped valve 13 has provided upon its upper portion an inclined seat 14c, cooperating with a similarly formed seat 15 on the part 16 of the oil cup, and thus controlling the escape of the lubricant from the chamber 12. The part 13 has formed therein, one or more passages 17,

leading from the upper surface thereof downwardly toward the lower point of the valve serving to conduct the lubricant therethrough to the point of the valve from which it may be easily observed through the sight opening 18 as it drops from the point of the valve. In the preferred construction the valve is provided with a transverse collar 19, with a raised portion 20 concentric with the guiding stem 21 of the valve, and the openings 17 at their top end are within the raised portion 20, as clearly shown.

As indicated in Fig. 2, one or more openings 21 through the transverse collar 19 are formed so that as the valve pulsates, or 15 operated, air may escape by the valve and upward into the chamber 12, and thence into the cup, serving to maintain an equalized pressure in the cup and other parts, and preventing any partial vacuum in the cup or chambers which might interfere with the regular operation of the device. The valve 13 is normally resiliently maintained at its upper limit of movement by the coil spring 23, the stem of the cup being sectional and joined together at that point by a suitable screw thread connection, to

permit the assembling of the device, as

clearly shown in the drawings. I

Below the valve 13 is arranged a transverse vaporizing plate 24, provided with a suitable number of openings 25 therethrough. This plate is removable, the approximate parts being sectional, and connected together by a screw-threaded connection, permitting an interchange of the plates 24, as may befound desirable or necessary.

In practical operation it is found that it is desirable to control or regulate the vaporizing action of the device, which may be done by a suitable valve (not shown) or more economically performed by providing plates 24: having the required number of openings therethrough to secure the same action. This is particularly true where the device is used on vacuum pumps, the apertures in plate 24 serving not only to control the draw of the device, as stated, but also controlling the degree of vaporization of the lubricant as it is delivered therethrough. With such a device as an air compressor, for example, this is not as necessary.

It will be seen that when used upon any cooperating part which pulsates or has an intermittent suction action, the valve will be actuated at each operation of said device, the impulse given to the valve being controlled to a large extent by the vaporizing plate 24:. As stated, a similar result may be obtained by placing a valve below the vaporizing plate, but obviously, it would increase the expense. For this reason a series of plates 24: maybe provided, and the particular one giving the best results employed.

In Fig. 5 the vaporizing plate 24 is shown with four apertures 25 therethrough, while in Fig. 6 a similar plate is shown with eight such openings. Obviously, the number of openings therethrough is optional, and the particular plate which is found most satisfactory may be used in securing the results desired.

It is found in practical operation that when my improved device has been once adjusted to the particular machine for which it is employed, it is unnecessary to further modify or adjust the same, owing to the stopping of the machine. Thus oil may pass out by the needle valve and into the chamber'12, and will be retained until the machine is started again, when at the beginning a slight excess of oil, owing to the said accumulation, is delivered. This, however, is an advantage, as such machines usually require a slight excess of lubricant when first started up. Obviously, after the excess of accumulated oil has been delivered, the device will operate in its normal manner described;

Having thus described my invention, itis obvious that various immaterial modifications may be made in the same without departing fromthe spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described, and uses mentioned.

What I claim as new and desire to secure by Letters Patent is 1. A device of the kind described, comprising an oil cup having a vertical oil duct leading therefrom, a rotatable stem positioned in the cup and terminating at its lower end in a needle valve controlling the passage of oil through the duct, and an oil chamber at the lower end of the duct, terminating in a suitable valve seat, in combination with a valve having its upper face formed to cooperate with the valve seat and normally resiliently maintained in contact therewith, ducts leading from the upper face of the valve to a point near the lower end thereof, and a vaporizing plate below the valve, through which the lubricant passes, substantially as described.

2. A device of the kind described, comprising an oil receptacle provided with a vertical oil duct extending therefrom, and a valve controlling the passageof oil from the receptacle into the duct, said duct terminating at its lower end in an oil chamber provided with a suitable valve seat, in combination with a valve having upon its face a cotiperating seat, ducts extending from the upper face of the valve to a point near the lower end thereof, through which the oil may pass, means for normally resiliently maintaining the valve to its seat, and means for controlling the operative impulse of the valve, substantially as described.

3. A device of the kind described, comprising an oil receptacle provided with a vertical duct extending therefrom, a valve controlling the passage of the oil from the receptacle into the duct, said duct terminating at its lower end in an oil chamber provided with a suitable valve seat, in combination with a valve having upon its surface a coiiperating seat, ducts leading from the upper face of the valve to a point near the lower end thereof through which the oil may pass, means for resiliently maintaining the valve to its seat, and means for regu lating the vaporization of the oil as it is delivered from the device.

4. A device of the kind described, com prising an oil receptacle provided with a vertical oil duct extending therefrom, a valve controlling the passage of oil from the receptacle into the duct, said duct terminating at its lower end with an oil chamber provided with a suitable valve seat, in combination with a valve having upon its face a cooperating seat, ducts extending from the upper face of the valve to a point near RUSSELL P.
